In 1557, Batolomé de Medina invented a new process for silver extraction. This process consisted on breaking, grinding and forming an amalgam of mercury and silver ore (known as backyard benefit or "beneficio de patio" in antique Spanish). After forming the amalgam, the silver was extracted by melting the mercury.
Mercury is extracted from cinnabar ores (HgS) by heating the ores in a current of air and collecting the vapor formed. The reaction for this extraction can be shown as: HgS + O2 → Hg + SO2. China has been the top producer of elemental mercury in the world with almost two-thirds global share of mercury ores [5].
The Mercury Leaching Process Flowsheet. The first part of the flowsheet consists of conventional single stage crushing which is typical of most small capacity plants. Crushing is usually performed on an eight hour period at a rate to provide sufficient crushed ore in storage to operate the balance of the plant "around the clock.".

Mercury deposits are globally distributed in 26 mercury mineral belts. Three types of mercury deposits occur in these belts: silica–carbonate, hot-spring, and Almaden. Mercury is also produced as a by-product from several types of gold–silver and massive sulfide deposits, which account for 5% of the world's production. Other types of mineral …
mercury processing, preparation of the ore for use in various products.. Mercury (Hg) has a unique combination of physical properties. Its low melting point (−38.87 °C [−38 °F]) and boiling point (356.9 °C [674 °F]), high specific gravity (13.5 grams per cubic centimetre), uniform volume expansion over the entire range of temperatures in its liquid state, and …
The ore dug from deeper levels was of lower grade and often unprofitable, causing some mines to be abandoned. The azoque (mercury amalgamation) process was developed in Europe and brought to Nueva España in the late 16th century. By the 18th century, it was widely used to produce high quality silver from low grade ore.
Mercury Ore Processing. The concentration of low grade cinnabar, HgS, with a specific gravity of 8.0-8.2 is effectively accomplished by gravity and flotation methods. Cinnabar ores of relatively high mercury content can be retorted directly to expel the sulphur and condense metallic mercury, but for lower grade ores, preliminary …
Crushing, a form of comminution, one of the unit operations of mineral processing.
